Description

Mastitis is one of the most economically important diseases in dairy production. Associated costs include treatment, culling, death and decreased milk production, and cow welfare is also compromised. This chapter reviews the indicators of mastitis and the contagious and environmental pathogens which cause it. It then discusses how mastitis can be managed and controlled on dairy farms, including consideration of dry cow therapy and the use of antibiotics.
